....vision, the occlusions is often considered as artifacts, undesirable in many applications, mainly for the image motion computation and the stereo matching. Consequently a number of algorithms have been designed to handle occlusions in order to estimate multiple image motions or the disparity field [5, 3, 2, 6]. Nevertheless, in this paper our focus is not on the explicit estimation of image motion (or disparity) but on the role of occlusions in motion perception. Assuming a moving monocular observer, our goal here is to study the advantages of perceiving occlusion points. Therefore we intend to find a ....

....approach described in the preceding paragraph might be extended to better exploit temporal continuity at and near boundaries. 4. Experimental Results This section presents results from controlled experiments run on synthetic data. Implementation details and results on real imagery are presented in Thompson (1995). While the limitations of using synthetic data are well known, it is the only way to do fair quantitative comparisons between alternate approaches. The accuracy of estimated flow was measured using the inter frame angular deviation described in Barron, 1994. While this measure is useful in ....
